Replacing a Line Module

The configuration of the back card may be slightly different depending on whether it is a single card or redundant card configuration. A standby card in a redundant card configuration may be removed without disrupting system operation even if it is a BCC. Removing a single card, however, will cause a system outage.

Caution Removing an active, single back card disrupts service on the node.

To remove a line module, perform the following steps:

Step 1 Check the status of the card using the dspcd or dspcds command. It should be failed or standby or replacement will affect operation of the node.

Step 2 If an active card needs to be replaced, “down” it first with the dncd command. Removing an active card affects operation only slightly if there is a standby card.

Step 3 Before removing a LM-BCC, make sure the standby BCC stby indicator is on steady. A flashing stby indicator indicates it is in the process of downloading either configuration data or software and is not ready to accept a transfer.

Step 4 For a single card configuration, disconnect the cables from the back card face plate. Make a note of the location of each cable so that it can be replaced correctly.

Step 5 For a redundant card configuration, disconnect the appropriate leg of the Y-cable connecting to the back card to be replaced. DO NOT REMOVE THE OTHER LEG GOING TO THE BACKUP CARD.
